Principia E Gravel is a high-performance E-gravel bike with superior handling. With a weight of just 14.5kg, the E Gravel feels and looks like an ordinary gravel bike. The design is minimalistic and clean with a well-integrated E-Bike system from MAHLE that is built to perform. Expect lots of power, high maneuverability and stability. E Gravel is perfect for commuting as well as a ride on forest tracks on the weekends.

On the bike you will find a frame-integrated MAHLE i250 downtube battery with a capacity of 250 WH, which is combined with a powerful X35+ rear wheel motor.

Ultra-light E-gravel bike

So light you won't believe it

With a weight of just 14.5 kg, the Principia E Gravel is at least as light as a regular hybrid bike. This positively affects the riding characteristics and makes the bike unusually manoeuvrable, agile, fast and fun. If you want to save some battery range or get more exercise, you will find that the E Gravel rides just like an ordinary hybrid bike when turning off the motor.

Display

Mahle iWoc ONE

In order to create a non-intrusive control experience, Mahle have designed the iWoc ONE remote to be integrated in the top tube. However, the iWoc switch is not just a regular on/off switch, but an intelligent system to control your E-Bike. The iWoc One allows the rider to toggle between the different support levels, while the colours of the LED ring indicate the support intensity, battery level and if a Bluetooth connection is established.

Motor

Mahle X35+

The MAHLE X35+ rear hub motor offers up to 40 Nm of natural and almost drag-free support. This system makes the E Gravel almost indistinguishable from regular bikes and provides style and utility alike that is unrivalled on the market.

Battery

MAHLE i250

The 250Wh battery capacity is engineered for the ideal weight and efficiency ratio. It has enough power to give the rider support for the whole day in the seat without the extra weight and bulk while being elegantly hidden inside the bike’s frame.

Tires

Panaracer GravelKing SK+

The Panaracer GravelKing SK+ is built for speed on even the roughest terrain. Aggressive studs, natural rubber compound and extra puncture protection, create the foundation for a true quality tire. The GravelKing SK+ has a strong grip on even incredibly loose gravel but maintains comfort. Despite its off-road characteristics, the GravelKing SK+ handles asphalt without problems and with minimal noise. Thanks to ProTite Shield Plus, the tire has even better protection against punctures.
